Phase change heat storage floor structure capable of enhancing heat exchange and construction method thereof

Abstract

The invention discloses a phase change heat storage floor structure capable of enhancing heat exchange and a construction method thereof, and belongs to the field of building energy conservation. Thefloor structure comprises a basic structure layer, a heat insulation layer, a phase change heat storage layer and a floor decoration layer from bottom to top in sequence. The phase change heat storagelayer comprises heating pipelines and phase change heat storage boxes, and the phase change heat storage boxes are filled with phase change materials. The floor structure is characterized in that theheating pipelines include the lower layer heating pipelines and the upper layer heating pipelines, the lower layer heating pipelines penetrate through the phase change heat storage boxes, and each upper layer heating pipeline is placed in a notch formed at the top of the side walls of the two corresponding adjacent phase change heat storage boxes. Through the double-layer arrangement of the heating pipelines, the arrangement density of the heating pipelines can be increased, during intermittent heating, the function of the upper heating pipelines is to quickly improve the room temperature tohelp heat storage, and the lower heating lines provide sufficient heat for heat storage of the phase change materials. Fins are connected between stainless steel pipes and stainless steel boxes to enhance heat exchange, so that the heat storage and heat release rates of the phase change heat storage floor can be greatly improved.

Description

technical field [0001] The invention relates to the field of building energy conservation, in particular to a phase change heat storage floor structure capable of enhancing heat exchange and a construction method thereof. Background technique [0002] In recent years, with the development of science and technology and market economy, people have continuously improved their living and working environment requirements, making the traditional radiator heating method no longer meet the demand. Radiant floor heating has the advantages of high comfort, energy saving, space saving, and effective use of low-temperature heat sources. For users in areas where centralized heating is not suitable and decentralized heating systems are used, in order to further reduce energy consumption while meeting actual heating needs, intermittent heating can be adopted. The shutdown operation mode can play a role in peak load shaving and valley filling for the grid load. [0003] A phase change mat...
